Deuteronomy 31

Let's be perfectly clear about something. The Israelites didn't take the Promised Land because none else wanted it. It was and remains some of the most strategic real estate on the globe. They didn't win it because the nations already there were weak. They weren't great empires, but they were very strong in their own right. The Israelites didn't conquer it because they were so overwhelmingly powerful; they were a bunch of riff-raff, the children of the same riff-raff that God had received from Egypt.

They got the land because God was with them.
